  Vulnerability Insight:

  It was discovered that long transformation matches in libxslt could
  overflow.  If an attacker were able to make an application linked against
  libxslt process malicious XSL style sheet input, they could execute
  arbitrary code with user privileges or cause the application to crash,
  leading to a denial of serivce. (CVE-2008-1767)
  
  Chris Evans discovered that the RC4 processing code in libxslt did not
  correctly handle corrupted key information.  If a remote attacker were
  able to make an application linked against libxslt process malicious
  XML input, they could crash the application, leading to a denial of
  service. (CVE-2008-2935)

  Affected Software/OS:
